What it means

RTF OLE2Link object is force-activated with \objupdate and fetches a remote second stage via an INCLUDE field.

Why it fires

Field-delivered OLE2Link auto-update attack path shared by CVE-2017-0199 and CVE-2017-8759: an OLE2Link object (Package/OLE2Link CLSID {00000300-0000-0000-C000-000000000046}) is auto-activated on open via \objupdate (no user interaction), and the remote loader URL is carried in an INCLUDETEXT/INCLUDEPICTURE field rather than an inline URL Moniker — so the moniker-based detector does not fire. The two CVEs share this exact RTF artifact and diverge only in the C2 response: CVE-2017-0199 returns an HTA/scriptlet (OLE URL-moniker / htafile handler), CVE-2017-8759 returns a SOAP WSDL the .NET SOAP-moniker parser compiles. With the C2 unreachable the specific CVE is reported as RELATED, narrowing to a single CVE (LIKELY) only when the moniker URL carries a tell (.txt/!soap/wsdl -> 8759; .hta/.sct/script: -> 0199).
